Color migration method of color images

Abstract

The invention discloses a color migration method of color images. The color migration method is used to adjust the tone of a present color image by taking a specific color image as reference, and the tone of a processed output image is similar to that of the reference image. The color migration method comprises the steps of establishment an intermediate image, meshing and color migration. The method can be used to realize color migration between color images automatically and more effectively without manual intervention, especially a better color migration effect can be obtained under the condition that the tone of the image to be processed is greatly different from that of the reference image.

Description

technical field

[0001] The invention belongs to the technical field of image processing, and in particular relates to a color migration method for a color image. Background technique

[0002] In image processing, it is often necessary to change the color of an image. For example, special effect processing and scene transformation of images in the film industry, beautification and rendering of characters in the photography industry, understanding and recognition of three-dimensional scenes in robot vision, image restoration and scene simulation reproduction in the military security field, etc. Color migration technology provides an effective method for changing the color of an image, but the current color migration method has a big deficiency: the color migration algorithm based on statistical matching is difficult to achieve when the source image and the target image are quite different. Satisfactory migration effect is obtained, so the scope of application is limited; the ...
